          COMPUWARE ACQUIRES PROVIDERLINK TO EXTEND COVISINT HEALTHCARE
                                   OFFERINGS

   COMPUWARE COVISINT TO ATTACK HEALTHCARE COSTS, IMPROVE QUALITY OF CARE FOR
               CUSTOMERS THROUGH POWERFUL PROVIDERLINK TECHNOLOGY


DETROIT--March 1, 2006--Compuware Corporation (NASDAQ: CPWR) today announced
that it has acquired privately held ProviderLink, of Cary, North Carolina.
Substantially all of ProviderLink's approximately 30 employees will join
Compuware.

"This transaction brings Compuware Covisint a powerful, web-enabled application
that -- through effective management and sharing of healthcare communications
and records -- reduces healthcare costs and increases quality of care," said Bob
Paul, President and COO, Compuware Covisint. "ProviderLink will represent a key
feature of Covisint's healthcare strategy, eliminating redundant and
hard-to-track phone, postal and telephonic business processes. This technology
and the team of people who develop, market and sell it are a natural fit that
will accelerate Compuware Covisint's penetration in the healthcare vertical."

Estimates suggest that as many as 70 percent of physicians still rely on
paper-based systems. ProviderLink supports paper-based healthcare organizations
such as these in interacting electronically with organizations of higher
technology sophistication. By making such communications bi-directional,
indexed, searchable and secure, ProviderLink cuts costs, eradicates redundancy
and improves care.

"ProviderLink complements Compuware Covisint's growing presence in the
healthcare industry," said David Gardner, CEO of ProviderLink. "By joining
forces, Compuware Covisint and ProviderLink can accelerate the adoption of a
solution that all healthcare delivery organizations, government agencies and
payors can use to more effectively manage all of their communications with each
other."

Commenting on the acquisition, former House Speaker Newt Gingrich, founder of
the Center for Health Transformation, said, "The partnership of Compuware
Covisint and ProviderLink tackles one of the most important challenges we face
in healthcare: getting information technology into the hands of the doctors and
professionals who treat patients. By addressing this challenge with a practical
approach, we can take a bold step forward in building a 21st century intelligent
health system -- a system that delivers better healthcare at lower costs."

Covisint enables companies of any size, location or technical sophistication to
securely share vital business information and applications with their trading
partners. As a leading provider of interoperability solutions,
